Can a facial mini-flap lift also soften one "moderately" deep horizontal forehead line (when expressionless)?

Facelift: Regardless of the type of face lift you are contemplating, it's important to recognize that a facelift in general only tightens and addresses the lower third of the face and the upper neck. Forehead lines can be addressed with surgery, too, but that is called a forehead or brow lift. They can be done a number of ways, which should be explored/explained by your surgeon.
